Abstract: PROBLEM TO BE SOLVED: To embody a liquid crystal display panel with which the occurrence of light leakage and the occurrence of discrination by a difference in the level of light shielding layers of a black matrix on array technique are suppressed. SOLUTION: The light shielding layers 105 consisting of a photosensitive black resin are formed via protective films 107 on TFT elements 102, gate lines 103, source lines 104 and the ends of pixel electrodes 106 on an array substrate 101. Perpendicular oriented films 110 are formed on the light shielding layers 105 and the pixel electrodes 106 and are rubbed. A horizontal oriented film 111 is formed on the counter electrode 109 of a counter substrate 108 and is rubbed in the direction orthogonal with the array substrate 101.

Abstract: PURPOSE:To detect satisfactorily a dynamic body by extracting a fixed pattern in an input data, and selecting the input data and a prescribed value in accordance with whether a difference between this fixed pattern and the input data is large or small. CONSTITUTION:An input data Xn from an FRA31 is supplied to a multiplier 1A, multiplied by a weighting coefficient A from a coefficient memory 2, and also a cumulative data Yn-1 from a data memory 3 is supplied to a multiplier 1B, and multiplied by a weighting coefficient B from the coefficient memory 2 in the same way. Also, signals from these multipliers 1A, 1B are supplied to an adder 4, and an added data is written to the memory 3. Also, said weighting coefficients A, B become the relation of A+B=1. As a result, an unchanged (fixed pattern) part between the input data Xn and the cumulative data Yn-1 becomes the next cumulative data Yn by a value as it is in the relation of A+B=1. On the other hand, a varied portion is attenuated in the ratio of the weighting coefficients A, B, and becomes the next cumulative data Yn.

Abstract: PROBLEM TO BE SOLVED: To obtain an antenna with a high C/N by providing an element to improve the transmission efficiency into each coupling hole in the antenna where lots of reception elements and transmission elements are coupled electromagnetically via each coupling hole. SOLUTION: An incoming radio wave is received by a reception element 20, in which a high frequency signal current is induced. The induced current is delivered to a transmission element 21 by electromagnetic coupling via a coupling hole 22. A transmission efficiency improving element 36 is interposed in the coupling hole to allow the transmission to be made with a high efficiency. The transmission efficiency improving element 36 is formed by forming an aluminum foil to be thin and long, selecting the length L3 slightly shorter than 1/4 of the propagation wavelength through a radial wave line 25 and arranging a conductor plate 16 contactless in parallel with the direction of the reception element 20.  Thus, lots of energy of the induced signal current is delivered to the transmission element 21, which sends a current corresponding to the signal to the line 25 and a probe 12 is used to extract much more signal currents.

Title: Semiconductor photo detector
Inventor: OKUHORA AKIHIKO
IPC: H01L31/10
Filed: 1991-09-09
Abstract: PURPOSE:To form a photo detector having a sensitivity to light of a long wavelength band transmitting a semiconductor substrate by a deformation superlattice structure. CONSTITUTION:A superlattice structure consisting of a GaAs layer and an InGaAs layer is formed on a GaAs substrate. A band gap DELTA2 of the InGaAs layer becomes shorter than the band gap DELTA6 of the GaAs layer or the band gap DELTA1 of the GaAs substrate, and as a result a sensitivity to light of a long wavelength band transmitting the substrate is provided. In the GaAs and InGaAs layers, a critical film thickness is limited since each lattice constant is different. However, a graded layer in which a potential is graded at parts of thickness x1 and x3 is formed on a lattice unmatching interface between the GaAs and InGaAs layers, and since the difference of each lattice constant is relaxed, a photo detecting can be performed under an effective film thickness.

Abstract: PURPOSE:To sufficiently prevent charge up in the peripheral part and the central part of an ion irradiation object.
